To make sure your website looks great and works all the time, no matter who’s looking at it from where, we Web designers have to do a lot of testing.
All browsers handle or “parse” HTML and CSS differently, and that also includes the different versions of the browsers. We physically view the sites on the different browsers during Web builds to see if everything is displaying and working correctly. For the most part Firefox, Safari and Chrome are very comparable in the way they handle code and display and are really the best choice for end users in general. Internet Explorer, however, is the beast of burden in the Web design industry and, unfortunately, is the most widely used.
